INCISION

INCISION is a brutal, fast, merciless blast from the past inspired by the godfathers of the first person shooter genre such as Doom, Quake, Blood, Shadow Warrior. INCISION offers an experience that demands skill and focus from its player, and rewards them with intense carnage that will paint the town red. Yours is a simple job. Cut, shoot, burn and decimate it all to stop the spread of the Growth. Mercy is weakness. Hesitation is death. INCISION is designed to be merciless in its difficulty, but the player will never feel weak in the face of danger. Your arsenal is varied, powerful, loud, and will easily turn enemies into sticky red puddles, as long as they don't first do it to you. Movement is fast and responsive. The story never gets in the way of the gameplay, but there is plenty of it be found for those who may seek to unravel its mysteries. Ten weapons of mass-slaughter, all including powerful alternative firing modes. Fire a volley of bouncing incendiary bombs out of your shotgun. Lob grenades from your heavy machine gun to turn your foes into red mist. Do tricks with your trusty revolver to maximize its damage output. Spray a volley of four incendiary rockets and watch even the strongest foe crumble into ashes before you. Go berserk with a saw-spear that works as a long-range slashing weapon or as a close-range buzzsaw. The world of INCISION has been transformed into a living nightmare where a ever-consuming, ever-growing mass of flesh and machine live in unholy symbiosis. All we hold familiar and comfortable has been turned into a network of hellish, rusty, pulsating labyrinthian series of factories that serve as the nerves and organs for some greater being that only seeks to merge, unite and grow. The Growth has seeks to unite and merge all life and technology alike, turning its people into machine-freaks, all of them designed to turn anyone who opposes its will inside-out. Augmented soldiers with burst-firing energy rifles, mad sycophants with ricocheting sawblades, machine spider-priests aka. "Spiderpopes" with homing missiles, and ancient things from beyond our world. INCISION's roster of monsters will keep you on your toes til the bloody end. What sets INCISION apart - and makes it so brutally satisfying - is its old-school extra lives system, with 1-ups scattered across the map to help you avoid death. You’d better hunt them down, because if you run out, the level restarts. No checkpoints. No quicksaves. Each level must be beaten in one go. INCISION challenges you to learn and adapt, sharpening your reflexes, your aim, your rage - until you’re no longer the prey, but the butcher of the nightmare spawn. Brutal. Unforgiving. But always fair. This is what a true FPS challenge tastes like. HEAD-BANGING & SKULL-RATTLING INCISION includes a soundtrack by Frédérick Chicoine "iNi"; An entire album's worth of atmospheric horror ambience and mayhem-inducing metal that will burst your veins with adrenaline.
